DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to the drawings, and initially to FIGS. 1-7, a display device in accordance with the present invention comprises a plug device 1 for engaging into a hole 31 of an article 30 for sales, and a hanger device 2 for engaging with the plug device 1, and for locking or anchoring the plug device 1 to the article 30 for sales, and for displaying the article 30 for sales, and for preventing the article 30 from being disengaged from the plug device 1 by unauthorized persons.

The plug device 1 includes a housing 10 and a plate 11 secured together, and a chamber 15 formed through the housing 10 and the plate 11. The housing 10 includes a slot 12 formed therein to increase a resilience or flexibility of the housing 10, and includes a spring blade 13 formed or provided therein, and defined by a peripheral gap 19, and located opposite to the slot 12 of the housing 10, and having a projection 14 extended therefrom and facing out of the housing 10.

It is preferable that the housing 10 includes a shape or an outer peripheral contour or a cross section similar to or equals to that of the hole 31 of the article 30, for allowing the housing 10 to be snugly fitted or engaged within the hole 31 of the article 30 (FIGS. 1 and 10-12) with such as a force-fitted engagement, and to prevent the housing 10 from being rotated relative to the article 30.

The resilience or flexibility of the spring blade 13 allows the projection 14 of the spring blade 13 to engage into the hole 31 of the article 30 (FIG. 11), and then to be biased to engage into a depression 32 of the article 30 (FIGS. 10, 12), so as to detachably latch or anchor or couple the housing 10 to the article 30. The plate 11 of the plug device 1 may be engaged with the article 30 (FIGS. 1, 10, 12), to allow the projection 14 of the spring blade 13 to be easily and precisely engaged into the depression 32 of the article 30.

As best shown in FIG. 4, the slot 12 of the housing 10 is also formed through plate 11, and the plate 11 includes a peg 16 extended into the slot 12 of the housing 10 (FIGS. 4, 6, and 9-12), for latching or anchoring hanger device 2 to the plug device 1, and for preventing the hanger device 2 from being disengaged from the plug device 1, which will be discussed in further details hereinafter.

The plug device 1 further includes a hook or a latch 17 extended from the housing 10 or from the plate 11, and slightly extended upwardly or outwardly beyond the plate 11, and partially extended into the chamber 15 of the plug device 1, and includes a peripheral recess 18 formed around the latch 17, for increasing the resilience or flexibility of the latch 17.

The hanger device 2 includes a board 20 for applying words or letters, or patterns, or marks, or advertisements thereon, and an opening 21 formed in the board 20 for such as hanging purposes, and includes an actuator 22 extended from or provided in the lower portion thereof, and engageable into the chamber 15 of the plug device 1, to engage with the spring blade 13 of the housing 10, and to force and retain the projection 14 of the spring blade 13 within the depression 32 of the article 30 (FIGS. 10, 12), and thus to lock or latch or anchor the housing 10 to the article 30.

The actuator 22 of the hanger device 2 includes one or more notches or cavities 27 formed therein, or relatively, includes one or more fins 23 extended therefrom, to form the notches or cavities 27 thereof, and to engage with the housing 10, and thus to stably attach or couple or secure the actuator 22 to the housing 10 with such as force-fitted engagements, or the like.

The actuator 22 of the hanger device 2 further includes a protuberance 24 extended therefrom, and slidably engaged into the slot 12 of the housing 10 (FIGS. 9-12), and engageable with the peg 16 of the plate 11 or of the housing 10 of the plug device 1 (FIG. 11), to limit the sliding movement of the actuator 22 of the hanger device 2 relative to the housing 10 of the plug device 1, and thus to prevent the actuator 22 of the hanger device 2 from being disengaged from the housing 10 of the plug device 1.

In operation, as shown in FIGS. 10, 12 and 14, when the actuator 22 of the hanger device 2 is deeply engaged into the chamber 15 of the plug device 1, and is engaged with the spring blade 13 of the housing 10, the actuator 22 of the hanger device 2 may force and retain the projection 14 of the spring blade 13 within the depression 32 of the article 30, in order to solidly lock the housing 10 to the article 30, and to prevent the actuator 22 of the hanger device 2 from being disengaged from the housing 10 of the plug device 1 and the article 30.

As shown in FIGS. 11 and 13, when the actuator 22 of the hanger device 2 is moved upwardly relative to the housing 10, and moved away from or disengaged from the spring blade 13 of the housing 10, or offset from the projection 14 of the spring blade 13, the spring blade 13 may be moved or bent or curved into the chamber 15 of the plug device 1, to allow the projection 14 of the spring blade 13 to be disengaged from the depression 32 of the article 30, and thus to allow the housing 10 to be disengaged or separated from the article 30.

As shown in FIGS. 3, 5, 7, the hanger device 2 includes a flap 25 extended from either the board 20 or the actuator 22, and engageable into the chamber 15 of the plug device 1, or engageable with the latch 17 of the plug device 1 (FIG. 7), to stably lock or anchor the actuator 22 in the chamber 15 of the plug device 1, and to prevent the actuator 22 from sliding relative to the housing 10 of the plug device 1, and thus to stably retain the actuator 22 of the hanger device 2 to the housing 10 of the plug device 1 and the article 30.

As shown in FIG. 8, it is preferable that the flap 25 of the hanger device 2 includes an inclined or tapered surface formed in the lower portion thereof, to engage with the latch 17 of the plug device 1, and to allow the flap 25 of the hanger device 2 to move beyond and to be engaged with or hooked by the latch 17 of the plug device 1. The engagement of the latch 17 of the plug device 1 with the flap 25 of the hanger device 2 may prevent the actuator 22 of the hanger device 2 from being disengaged or separated from the housing 10 of the plug device 1 and the article 30 by unauthorized persons.

As shown in FIGS. 11-14, when the latch 17 is cut or removed from the plate 11 or the housing 10 of the plug device 1 by users, the flap 25 and thus the actuator 22 of the hanger device 2 may slide relative to the housing 10, to allow the projection 14 of the spring blade 13 to be selectively disengaged from the depression 32 of the article 30 (FIG. 11) when the actuator 22 of the hanger device 2 is offset from the projection 14 of the spring blade 13, and thus to allow the housing 10 to be detachably or reusably locked to the article 30.

The flap 25 and the actuator 22 of the hanger device 2 may be snuggly fitted or engaged in the chamber 15 of the housing 10 with such as force-fitted engagements, to retain the projection 14 of the spring blade 13 to be engaged within the depression 32 of the article 30, and to detachably lock the actuator 22 of the hanger device 2 to the housing 10 of the plug device 1, and thus to allow the display device to be used again to detachably lock the article 30 to the plug device 1 with the hanger device 2.

It is to be noted that the actuator 22 of the hanger device 2 is required to simply engage into the chamber 15 of the housing 10 without rotational movement, and the actuator 22 of the hanger device 2 includes a greatly simplified configuration that may be easily and quickly manufactured with decreased manufacturing costs.

Accordingly, the display device in accordance with the present invention includes a lockable and reusable configuration and including a simplified configuration that may be easily and quickly manufactured with decreased manufacturing costs.
